Tuning Many-Body Interactions in a Thin Topological Insulator

ORAL

Abstract

The conical dispersion of spinless Dirac fermion systems can become renormalized upon introduction to electron-electron interactions. It is an open question whether or not this behavior extends to the spin-momentum locked surface states of Topological Insulators. We investigate in Photoemission Spectroscopy the surface states of a thin Topological Insulator Bi2Se3 on SrTiO3 using temperature as a knob to tune electron-electron interactions.
